Failed to open a session for the virtual machine

Post by StefanS »

Hi

After I upgraded my VM installation to Version 5.2.6 r120293 (Qt5.6.2) i got the error message

"Failed to open a session for the virtual machine Lubuntu.
The VM session was closed before any attempt to power it on.
Result Code: E_FAIL (0x80004005)
Component: SessionMachine
Interface: ISession {7844aa05-b02e-4cdd-a04f-ade4a762e6b7}"

I tried some solutions from the net without success.
Then I just got a idea, so I made a clone of my environment from VM, and the clone works fine.
So it works but I dont know why cloning the environment made the trick.

Unless we see a VBox.log, we know as much as you do...
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.
